The Missouri State Penitentiary (MSP) was decommissioned in 2004 and now serves as a great historic landmark in downtown Jefferson City. Visitors can choose to take a history, ghost, or photography tour, and will walk through several incredibly historic housing units, the vast upper yard of the property and the gas chamber, where 40 men and women were executed. Also available are paranormal investigations where you will hear about the first-hand ghostly sightings at MSP and hunt for paranormal activity! Have a group of students looking for an unforgettable learning experience? All of our tour types can be adapted for student groups!
